Vibration/noise from right side of backseat of ModelY

There are two ways I have found to avoid the seat belt rattle/vibration. One is to buckle the belts and the other is to route them around the head rest (this is the method I use now). The idea is to get them away from the plastic trim in between the seat and door on each side.

This is a common and annoying issue on Model Y.
 
Another thing to check is the headrest. You can use a paperclip to loosen it, then remove it entirely to test. I was mostly able to silence them by jamming them all the way down (below the bottommost locking position).
